CARWH EL.

SPECIFICATION forming part of Letters Patent No. 626,517, dated June 6,1899.

Application filed April 3, 1899. Serial No. '711)627, (No model.)

. is a full, clear, and exact description, reference being had to theaccompanying draw- `ings, forming a part hereof.

My invention relates to car-wheels; and it consists of the novelconstruction, combination, and arrangement of parts hereinafter shown,described, and claimed.

Figure l is a side elevation of the car-wheel, a portion thereof beingbroken away. Fig. 2 is a verticalsectional view taken diametricallythrough the center of the car-wheel, the same being shown in positionupon an axle and the end of said axle in an ordinary journal-box.

My improved car-wheel is of the usual form and construction, cast in onepiece, with the usual hub l, web 2, rim 3, and liange 4; but my improvedcar-wheel differs from the ordinary car-wheel in that an annular fiange5 is formed integral with the outer face of the web 2, said iian gebeing so formed in cross-section as that a slight recess or continuousgroove 6 is entirely formed, the same extending entirely around on theinside of said flange 5. The wheel so constructed is located upon theend of the axle in the usual manner, and the end of said axle operatesin the usual oil or journal box 7. The usual brasses or brassbearing-plates are arranged in the journalboxes immediately above theportions of the axles which operate in said boxes, the position of saidbrasses being shown in dotted lines, and wh en these brasses become wornor broken Athey must be removed, and thepper- `ation incident to theremoval of said brasses is at present somewhat difficult and requiresconsiderable time and labor. The usual procedure for removing saidbrasses is to elevate the journal-box by a jack or other suitable meansuntil the wheel is clear of the rail.

Then the axle is depressed in various ways by means of levers and blocksuntil said brasses can be removed from between the journals of the axleand the top of the journal-boxes. This operation is, as heretoforestated, very difficult and requires much time and labor; but wherewheels of my improved construction are used said operation can beaccomplished very quickly and with little labor. After the journal-boxis elevated a bar or 1ever is passed beneath said journal-box, with thepoint of said bar or lever engaging in the groove 6 within the fiange 5.Then by apply ing suflicient power to the outer end of the lever thewheel and end of the axle are de pressed or moved downwardly asufficient distance to allow the removal of the brass plates within thejournal-boxes.

The car-wheels of the present construction are not provided with thisflange. it is impossible to engage the point of a bar upon the outerface thereof to depress said carwheel and-the axle.

I claiml. A car-wheel, comprising the usual hub, web and rim andprovided with the concentric annular flange 5 upon its outer face, uponthe inside of which flange is formed the continuous groove G, saidflange being of abrupt form and adapted to support the end of ahand-lever, substantially as specified.

2. A car-wheel, constructed with a continuous odset in its outside face,which oset is concentric with the periphery of the wheel, which offsetis of sufficient depth to receive the point of a hand-lever,substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.A
